What 7Hz Salnotes Zero 2 owners say

“the Linsoul Zero:2 absolutely shock me at how good they sound driven by my old Samsung Note 9, no dongle, no nothing. I have weird small ear canals for a big guy, and these fit perfectly with the pink tips that came stock on them.”
— @thedavemusgrave on YouTube
“is now quite content with the IEM.”
— @bosansekali898 on YouTube
“the original Zero is one of the most annoying IEMs I've used when it comes to the tips.”

What Letshuoer S12 Pro owners say

“The S12 is brighter than the HeyDay (to my ears), so I would recommend a warmer amp source to really make them shine, and I would assume that they would pair great with tube amps”
— GlenAppleton on Head-Fi
“I just love my S12 PRO.”
— @fhreire on YouTube
“The bass on most planars including the S12PRO decays quickly. Gives the entire sound profile a lighter note weight and no amount of tip rolling will change that aspect (I went through 12 pairs).”
